Thin Winged Bugs

(Family Henicocephalidae.)
This is a remarkable family of which only twelve species are known, of which two inhabit the United States. It is allied to the Reduviidae, but the front wings are wholly membranous, with a distinct venation resembling those of certain saw-flies. The front legs are greatly swollen. The American species are Henicocephalus culicis Uhl. and H. formicinis Uhl. The farmer was found by Mr. E. A. Schwarz under stones on the shores of the Great Salt Lake, Utah, and later on the shores of the Potomac River near Washington.
